PERFORMANCE ORDER
1. Clear a back part of the loose leaf and a place of its installation in a rod and a rod cover.
2. Establish loose leaves on the places.
3. One of methods consists in establishing covers шатунных bearings together with the loose leaf on rods and to screw their demanded moment. Measure internal diameter of each collected pair loose leaves of bearings. Measure diameter of everyone шатунной necks of a cranked shaft. Subtract from the measured diameter of the bearing the corresponding diameter шатунной necks of a cranked shaft.
4. The second and more exact method consists in using a product known as Plastigage. It is a round plastic core which is compressed between the loose leaf and a neck of a cranked shaft. After cover removal шатунного the bearing the deformed plastic core is measured by a special template which is available complete with Plastigage. Procedure for use Plastigage the following. Establish without greasing rods on a cranked shaft, necks of a cranked shaft and loose leaves should be absolutely pure and dry. Cut off some slices of a plastic core and establish them on each neck of a cranked shaft. Establish covers with the bottom loose leaves and tighten bolts of fastening by the demanded moment.
5. In the course of measurement of a backlash by method Plastigage do not rotate a cranked shaft of the engine. Unscrew a cover of fastening of the loose leaf, remove it and to the deformed plastic core put the scale ruler printed on packing. Comparing width of the deformed plastic core with control width on a scale ruler, define backlash size. In end carefully clear traces Plastigage – a material from loose leaves and a cranked shaft.
